The damage was seen both to DNA and its ability to fix itself, making cells more likely to mutate and develop into cancer, said lead researcher Moon-shong Tang, a professor of environmental medicine at New York University School of Medicine. Results also demonstrated that vaping may be less addictive than smoking, as shown by longer delay times in the morning before vaping and a trend of reducing nicotine levels in e-cigarette liquid over time.

"This study shows nothing at all about the dangers of vaping", Peter Hajek, director of the Tobacco Dependence Research Unit at Queen Mary University of London told the Guardian.

If Tang's findings are verified, they would add more impetus for public policies to require lower nicotine levels in tobacco cigarettes and to increase regulation of e-cigarettes, said Herbst, who was not involved with the current research.

In 2016, the FDA finalized a rule extending its regulatory authority to all tobacco products, including e-cigarettes, cigars, as well as hookah and pipe tobacco, as part of its goal to improve public health.

"Based on these results, we propose that [e-cigarette vapour] is carcinogenic and that E-cig smokers have a higher risk than nonsmokers to develop lung and bladder cancer and heart diseases", reads the research. NNAL, another member of the nitrosamine family that damaged the smoking mice's DNA, was found to be reduced by 97% in E-cigarette smokers as opposed to tobacco smokers in another recent study. DNA-repair activity and the fix proteins XPC and OGG1/2 were reduced in the lung tissue of mice. A study in mice, published today in Proceedings of the National Academy of Sciences, is sure to provide fodder for both sides.

To examine whether this effect also occurred in humans, the team exposed human lung and bladder cells to nicotine and its nitrosamine by-product.

The study's authors recommend that further long-term studies are needed.

Electronic cigarettes may be helpful in aiding traditional smokers to quit, but research suggests that these devices are far from harmless, Aoife Muckian investigates. Instead they contain nicotine, which is what keeps people addicted, but is not responsible for the major health harms from smoking.
